Put the dates and water in a blender and blend until smooth. Save in a jar.
For the bread:
First, preheat the oven to 350°F. Then, in a bowl, beat the oil with the date paste, then add the eggs and keep beating. Add the mashed bananas and milk, mix until well combined, then add the baking soda, salt, and cinnamon. Mix well.
Finally, add the flour, raspberries, and beat well.
Pour the mixture into a rectangular baking pan, and bake for 1 hour or until you can poke it with a knife and it comes out clean.
